1. Preparation:
* Safety First: Disconnect the negative battery cable to prevent accidental short circuits.
* Gather Tools: You'll likely need a wiper arm puller tool (highly recommended to avoid damaging the wiper arm or the spindle). If you don't have one, a flat-head screwdriver *might* work, but it significantly increases the risk of scratching the car's paint or damaging the wiper arm or spindle. Some strong pliers *might* also work, but again, increase the risk of damage.
* Clean the area: Clean the area around the wiper arm pivot point to remove any dirt or debris that might hinder your work.
* Locate the nut (if any): Some wiper arms have a nut securing them to the spindle. Check for this before proceeding. If there is a nut, remove it first.
2. Removing the Wiper Arms:
* Use a Wiper Arm Puller: This is the safest and most effective method. Follow the instructions that come with the puller. Generally, you clamp the puller onto the wiper arm, then carefully tighten the puller to pull the arm away from the spindle.
* Alternative (Risky) Methods: If you don't have a puller:
* Flat-head screwdriver method: Carefully place the flat-head screwdriver between the wiper arm and the spindle, using it as a lever. Pry gently and slowly. This is risky and prone to scratching.
* Pliers method: Use strong pliers to carefully grip the wiper arm close to the spindle and gently pull. Again, this is risky.
Important Considerations:
* Spindle Damage: Be extremely gentle. The wiper arm spindle is delicate, and forceful prying can easily bend or break it.
* Spray Lubricant: Consider spraying a little penetrating oil (like PB Blaster) onto the wiper arm pivot point before attempting removal. This can help loosen it up.
* Position of Wiper Arm: It's helpful to have the wiper blades in the "park" position, as this might give you better access.
3. Reinstallation:
Reinstalling is the reverse process. When using a puller, ensure that the arm is properly seated and aligned on the spindle before releasing the puller.
If you are uncomfortable doing this yourself, take your vehicle to a professional mechanic. Replacing the wiper arms is a relatively inexpensive repair, and a mechanic has the right tools and expertise to avoid causing damage. The cost of replacing a damaged spindle will far outweigh the cost of professional wiper arm removal.
